COIN-CONTROLLED VENDING-MACHINE.

Application filed, September, 26, 1919.

To all whom it may concern.-

Be it known that I, HARRY HANsoN, a citizen of the United States, and. a resident of lVatertown, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Coin Controlled, Vending Machines, of which the following is a full, clear, and exact specification.

This invention relates to machines for vending cards, postals, paper and envelops and the like, and has for its object the effecting of simplified means for enabling a coin to release the delivery device, for showing when the machine is empty; for locking the coin receiver, and for effecting certain improvements indetails of construc tion hereinafter set forth.

In the drawings forming part of this specification, Figure 1 is a side sectional view of a vending machine embodying my improvements. Fig. 2 is a side sectional view of the same showing the coin delivery devices. Fig. 3 is a simllar sectional view showing the coin as unlocking the delivery devices. Fig. 4: isa sectional plan view of a art of the machine.

he reference numeral 1 designates the back of the vending machine case, 2 the sides, 3 the removable front, 4 the bottom of the coin receiver and 5 the top of the coin receiver and bottom or floor of the article containin chamber.

Upon the floor 5 rests the delivery frame comprising cross members 6 and 7 and longitudinal members 8 and 9, the member 6 having a knob 10 for enabling the frame to be withdrawn more or less from beneath the front or door 3. Upon the members 8, 9 are secured wires 11, and upon these wires rest the pile of cards, envelops or the like, as 12. For enabling the withdrawal of the frame to bring with it the undermost one of the articles 12, the frame member 7 is provided with plates 13, preferably one near each side, having each an upturned lip let at its rear end, as shown in Figs. 1 and 4:, which is just high enough to seize the lowermost card or envelop but none of the others.

A cord attached to the frame member 7 and passing thence about a pulley 16 to a suitably anchored spring 17, serves to draw the delivery frame back into place after its withdrawal and release. lref- Specification of Letters Patent.

'to the side 2, a slot Patented Aug'.,1 7, 1920. Serial No. 326,663.

erably the spring will retract the frame back far enough to present its lips 14 behind the front surfaces of the rails 19 with which the-back 1 is provided, in order to make sure that no envelops can rest on top of the lips 14 and so escape removal. In Fig. 1, however, the delivery frame is not shown thus retracted to its normal limit.

Upon the pile of envelops or the like, is laid a weight 20 centrally apertured and having a flap 21 pivoted at 22 therein. Above the free end of the flap 21 is pivoted a. plate 23 bent approximately at right angles to itself, and connected with the flap by. a wire 24. So long as any one or more of the envelops are between the weight and the delivery frame, the elbow-plate 23 remains with its free portion nearly horizontal; but when the last envelop has been withdrawn the flap descends between the frame members and thereby lowers the elbow-plate to present its portion 25 substantially vertical and immediately behind the small window 26. The portion 25 having been inscribed with a suitable word or characteristic sign indicating the emptiness of the case, no customer will deposit his coin therein.

The designated coin is introduced into a chute 27 and descends therein to a leaf spring 29 attached to the delivery frame, preferably to the frame member 8 and close or notch 30 being provided in the spring, into which the coin enters. The rear end of the spring 29 is formed with a hook 31 adapted normally to engage a pin 32 projecting from the side 2 and thereby to prevent the delivery frame from being withdrawn more than a quarter of an inch or thereabout. lVhen, now, the coin is resting in the slot or notch 30 as shown in Fig. 2, and the delivery frame is drawn outwardly, the coin comes against a pin 33 projecting from the side 2, and the only way whereby the coin can pass this pin and the delivery frame have its hook 31 put out of reach of the stop pin 32, is for the spring 29 to flex downward as shown in Fig. 3. After this has occurred, the delivery frame can be withdrawn sufiiciently for the envelop delivered thereby to be seized and taken out, the frame member 6 being formed with a groove 34 for better enabling the finger tips to get hold of the envelops edges. WVhen the delivery frame has thus been drawn out the proper distance,

the coin will become dislodged from the spring 29 and will descend through the slot in the floor 5 and fall into the coin receiver below.

For permitting the removal of the coins which have accumulated on the bottom 4t of the coin receiver, a movable front 36 is fitted to the receiver, as shown in Fig. 1, a pin or two 37 projecting from the bottom edge of the front into holes 89 in the bottom l, \vhile from the upper part projects an arm etO having an opening entered by a removable bolt 41 descending through the roof or floor- 5, its head d2 being accessible through a space between the frame members. The door 3 having been removed, the replenishers fingers can easily reach the head 4:2

a slidable article-removing member, a fixed stop, a leaf spring supported at one'end by said member and having a hooked free end adapted normally to engage said step, said spring having an opening disposed to par-V tially receive a designated coin, and a sta tionary device, whereby, a designated coin eing deposited in said opening, the withdrawal of the article-removing member will cause the spring to press the coin against the stationary device and to be itself sufficiently depressed to permit its hooked end to freely pass said fixed-stop.

2.6. coin controlled vending machine comprising a slidable article-removing memher, a fixed'pin, a leaf spring supported at one endbysaid member having a hook at its free end and a notch in its side, a stationary pin, and means for depositing a designated coin in said notch, whereby the withdrawal of the article-removing member causes said spring to press such coin against said stationary pin and thereby to depress its hooked end out of possible engagement with said fixed pin. a

In testimony that I claim the foregoing invention, I have hereuntoset my llitllCltlllS 25th day of September, 1919. v
